When Driving
i-ACTIVSENSE
Forward Sensing Camera (FSC) *
Your vehicle is equipped with a Forward Sensing Camera (FSC). The Forward Sensing
Camera (FSC) is positioned near the rearview mirror and used by the following systems.
 


 High Beam Control System (HBC)



 Lane Departure Warning System (LDWS)

Forward Sensing Camera (FSC)
The Forward Sensing Camera (FSC) determines the conditions ahead of the vehicle while
travelling at night and detects traffi c lanes. The distance in which the Forward Sensing
Camera (FSC) can detect objects varies depending on the surrounding conditions.

When Driving
i-ACTIVSENSE
CAUTION
Heed the following cautions to assure the correct operation of the Forward Sensing
Camera (FSC).
 
 Do not remove the Forward Sensing Camera (FSC) cover. 
 Do not place objects on the instrument panel which refl ect light. 
 Do not apply accessories, stickers or fi lm to the windscreen near the Forward Sensing
Camera (FSC). If there are objects in front of the Forward Sensing Camera (FSC) lens,
even a transparent sticker, they will cause the system to not operate correctly.
  Always keep the windscreen glass around the camera clean by removing dirt or
fogging. Use the windscreen defroster to remove fogging on the windscreen.
  When cleaning the windscreen, do not allow glass cleaners or similar cleaning agent to
get on the Forward Sensing Camera (FSC) lens. In addition, do not touch the Forward
Sensing Camera (FSC) lens.
  Consult an expert repairer, we recommend an Authorised Mazda Repairer regarding
cleaning the interior side of the windscreen around the Forward Sensing Camera
(FSC).
  Be careful not to scratch the Forward Sensing Camera (FSC) lens or allow it to get
dirty. Also, do no take the camera apart. Otherwise, it could result in damage or
malfunction.
  Consult an expert repairer, we recommend an Authorised Mazda Repairer before
performing repairs around the Forward Sensing Camera (FSC).
  The Forward Sensing Camera (FSC) is installed to the windscreen. Consult an expert
repairer, we recommend an Authorised Mazda Repairer for windscreen repair and
replacement.
  When performing repairs around the rearview mirror, consult an expert repairer, we
recommend an Authorised Mazda Repairer.
  Consult an expert repairer, we recommend an Authorised Mazda Repairer regarding
cleaning of the Forward Sensing Camera (FSC) lens.
  Do not hit or apply strong force to the Forward Sensing Camera (FSC) or the area
around it. If strong force is applied, stop using the Lane Departure Warning System
(LDWS) and the High Beam Control System (HBC), and consult an expert repairer,
we recommend an Authorised Mazda Repairer.
  The direction in which the Forward Sensing Camera (FSC) is pointed has been fi nely
adjusted. Do not change the installation position of the Forward Sensing Camera
(FSC) or remove it. Otherwise, it could result in damage or malfunction.

*Some models.4–150
When Driving
i-ACTIVSENSE
Radar Sensor (Front) *
Your vehicle is equipped with a radar sensor (front).
The following systems also use the radar sensor (front).
 


 Smart Brake Support (SBS)



 Mazda Radar Cruise Control (MRCC)



 Distance Recognition Support System (DRSS)
The radar sensor (front) functions by detecting the radio waves refl ected off a vehicle ahead
or an obstruction sent from the radar sensor (front).
The radar sensor (front) is mounted behind the front emblem.
Radar sensor (front)
If the Smart Brake Support (SBS) warning light (amber) is illuminated, the area around the
radar sensor (front) may be dirty. Refer to “Warning Guidance” in the centre display (Type
B audio).
Refer to If a Warning Light Turns On or Flashes on page 7-32 .

4–151
When Driving
i-ACTIVSENSE
CAUTION
Heed the following precautions to assure correct operation of each system.
 
 Do not adhere stickers (including transparent stickers) to the surface of the radiator
grille and front emblem in and around the radar sensor (front), and do not replace
the radiator grille and front emblem with any product that is not a genuine product
designed for use with the radar sensor (front).
  The radar sensor (front) includes a function for detecting soiling of the radar sensor's
front surface and informing the driver, however, depending on the conditions, it may
require time to detect or it may not detect plastic shopping bags, ice or snow. If this
occurs, the system may not operate correctly, therefore always keep the radar sensor
(front) clean.
  Do not install a grille guard. 
 If the front part of the vehicle has been damaged in a vehicle accident, the position of
the radar sensor (front) may have moved. Stop the system immediately and always
have the vehicle inspected at an Authorised Mazda Repairer.
  Do not use the front bumper to push other vehicles or obstructions such as when
pulling out of a parking space. Otherwise, the radar sensor (front) could be hit and its
position deviated.
  Do not remove, disassemble, or modify the radar sensor (front). 
 For repairs, replacement or paint work around the radar sensor (front), consult an
Authorised Mazda Repairer.
  Do not modify the suspension. If the suspension are modifi ed, the vehicle's posture
could change and the radar sensor (front) may not be able to correctly detect a vehicle
ahead or an obstruction.

4–152
When Driving
i-ACTIVSENSE
NOTE
  In the following cases, the radar sensor (front) may not be able to detect vehicles ahead
or obstructions.
 


 The rear surface of a vehicle ahead does not refl ect radio waves effectively, such as
an unloaded trailer or an automobile with a loading platform covered by a soft top,
vehicles with a hard plastic tailgate, and round-shaped vehicles.
 


 Vehicles ahead with low vehicle height and thus less area for refl ecting radio waves.



 Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its
tyres and onto your windscreen.
 


 The boot/luggage compartment is loaded with heavy objects or the rear passenger
seats are occupied.
 


 Ice, snow, or soiling is on the front surface of the front emblem.



 During inclement weather such as rain, snow, or sand storms.



 When driving near facilities or objects emitting strong radio waves. 

 In the following cases, the radar sensor (front) may detect vehicles in the opposite
lane or surrounding obstructions, or it may not be able to detect vehicles ahead or
obstructions.
 


 The beginning and end of a curve.



 Roads with continuous curves.



 Narrow lane roads due to road construction or lane closures.



 The vehicle ahead enters the radar sensor's blind spot.



 The vehicle ahead is running abnormally due to accident or vehicle damage. 



 Roads with repeated up and down slopes



 Driving on poor roads or unpaved roads.



 The distance between your vehicle and the vehicle ahead is extremely short.



 A vehicle suddenly comes close such as by cutting into the lane. 

 To prevent incorrect operation of the system, use tyres of the same specifi ed size,
manufacturer, brand, and tread pattern on all four wheels. In addition, do not use
tyres with signifi cantly different wear patterns or tyre pressures on the same vehicle.
(Including the temporary spare tyre)
  If the battery power is weak, the system may not operate correctly. 
 When driving on roads with little traffi c and few vehicles ahead or obstructions for the
radar sensor (front) to detect, Smart Brake Support/Smart City Brake Support (SBS/
SCBS) warning light (amber) temporarily illuminates, however, this does not indicate
a problem.

*Some models.4–153
When Driving
i-ACTIVSENSE
Laser Sensor (Front) *
The Smart City Brake Support (SCBS) laser sensor (front) is installed at the top of the
windscreen near the rearview mirror.
Laser sensor (front)
Always keep the surface of the windscreen around the laser sensor (front) clean to assure
proper operation of the Smart City Brake Support (SCBS) system.
WARNING
As there is the possibility of eye damage occurring from the laser, always heed the
following precautions:
 
 Never remove the sensor. 
 A removed sensor will not meet the conditions for a class 1M laser under the IEC
60825-1 specifi cation and therefore eye safety cannot be assured.

 Do not peer into the sensor using optical instruments with a magnifi cation function
such as magnifying glasses, and microscopic and objective lenses within a distance
of 100 mm (3.94 in) from the sensor.
